I have just received an email from Blue Isle Studios stating that Slender: The Arrival is coming to Steam this Halloween with new content! Make sure to pick it up when it arrives. I want you guys to have the scare of a lifetime this Halloween! Mhahahahahahahahaha!
I honestly had high hopes for this demo but unfortunately the language barrier hinders effective game play. Hopefully Digital Happiness will have this little hiccup fixed before they officially release the full version.
